Real Valladolid defender Fernando Calero is in London sparking Arsenal transfer rumours.
Calero, 23, has been tipped to join the Gunners in January, says The Sun.
And last night he shared a snap of himself in the capital, staying at the H10 Waterloo hotel on Southbank.
Centre-back Calero played in Saturday’s 1-1 draw with Athletic Bilbao and hopped on a plane to England shortly after.
Earlier this month, the Gunners were linked with the young defender, as they currently sit in the midst of a defensive crisis.
As well as Rob Holding – out for the season – Unai Emery is currently missing FIVE other defenders for the festive schedule.
